The Adjunct 2500/2550 is a mechanically operated chain-mounted door closer. It closes your doors practically invisibly.
The door closer consists of an aluminium tube inserted in the door with spring, pull rod and chain. The construction is fixed by means of a fastening plate screwed onto the tube.
The closing force is transmitted by the chain, which runs over a hardened steel prop and is hooked into the keyhole-shaped opening of a frame plate.
The Adjunct 2500/2550 is in combination with a DICTATOR door catcher a good and cost effective alternative to a door closer.
Available with both rectangular frame plates and frame plates with rounded corners (for machine processing). The content of the 'finish/material' column refers to the frame plates.
Type 2500, diam. 16 mm, for normal doors, 5-15 N closing force
Type 2550, diam. 22 mm, for heavy steel or wooden doors, 15-30 N closing force.
